Rust

The AMD Ryzen 5 7400F and AMD Radeon RX 580 combination delivers a playable but constrained experience in Rust, with performance firmly bottlenecked by the graphics card at higher resolutions. Benchmark data shows this pairing ranks in the bottom 10% of tested configurations, making it suitable primarily for 1080p gaming at medium settings.

Resolution Scaling

The FPS drop from 1080p to 4K reveals a classic GPU-bound scenario. At Low settings, the average frame rate falls from 74 FPS at 1920x1080 to 51 FPS at 2560x1440, a 31% reduction, and then to 30 FPS at 3840x2160, a 59% drop from the 1080p baseline. This steep decline indicates the RX 580's pixel throughput is the limiting factor; the Ryzen 5 7400F's six Zen 4 cores are not the constraint here.

The scaling pattern is consistent across all settings presets. High settings produce 42 FPS at 1080p, 29 FPS at 1440p, and 17 FPS at 4K. Medium settings show 49 FPS, 34 FPS, and 20 FPS respectively. Ultra settings yield 32 FPS, 22 FPS, and 13 FPS. The ratio between 1080p and 4K performance remains roughly 2.4x across presets, confirming that the RX 580's rendering pipeline saturates well before the CPU's capability is exhausted. Rust's demanding draw call overhead does not manifest as a CPU bottleneck here because the GPU is overwhelmed first.

The RX 580's 256-bit memory bus and 256.0 GB/s bandwidth provide adequate data throughput for 1080p, but the card's 32 ROPs and 6.175 TFLOPS of FP32 compute struggle to fill 4K frames. At 1440p, the combination of 29-51 FPS depending on settings suggests a middle ground where the GPU is still the primary limiter, but the margin narrows. The data indicates that users should target 1080p for acceptable performance; 1440p is only viable at Low settings, and 4K is effectively unplayable across all presets.

How This Combo Ranks

The combo's rank of 2683 out of 2953 tested configurations places it in the 9th percentile, meaning roughly 91% of tested combos outperform it in Rust. This low ranking is primarily attributable to the RX 580, which sits at the 53rd percentile versus all GPUs and has an average benchmark score of 12928. The GPU's nearest rivals include the NVIDIA GeForce RTX 3050 Ti Mobile (avg score 12940, delta -0.1%) and the NVIDIA GeForce GTX 1660 SUPER (avg score 12986, delta -0.4%), indicating the RX 580 performs nearly identically to those parts in synthetic tests.

In contrast, the Ryzen 5 7400F is a strong CPU, ranking in the 83rd percentile versus all CPUs with an average benchmark score of 32750. Its nearest rivals are the Intel Core i5-14600T (avg score 32707, delta 0.1%) and the AMD Ryzen 7 PRO 6850H (avg score 32812, delta -0.2%). This CPU performance is far above what the RX 580 can utilize in Rust. The data shows a significant imbalance: the CPU sits in the top 17% of all processors, while the GPU sits in the middle of the pack. This mismatch means the combo's overall ranking is dragged down by the GPU, and upgrading the graphics card would yield the largest FPS improvement.

The rank of 2683 is consistent with the measured FPS data. At 1080p Low, the 74 FPS average is competitive with older mid-range systems, but at 4K Ultra, the 13 FPS average is among the lowest scores recorded. The combo's performance profile is predictable: it excels at low-resolution, low-settings gaming but falls apart under high graphical loads. Users comparing this combo to others in the database should expect it to outperform only the bottom 9% of tested systems, which likely feature older integrated graphics or entry-level discrete GPUs.

Measured FPS Breakdown

The measured FPS data covers four resolutions and four settings presets, providing a complete picture of performance. At 1920x1080, the full range of settings is playable to varying degrees. Low settings deliver an average of 74 FPS, which is smooth for most players. Medium settings produce 49 FPS average, with a minimum of 42 and maximum of 57 FPS, indicating some frame pacing issues but acceptable for a survival game. High settings yield 42 FPS average, and Ultra drops to 32 FPS average. The step from Low to Medium costs 25 FPS, while the step from Medium to High costs 7 FPS, and High to Ultra costs 10 FPS.

At 2560x1440, performance becomes marginal. Low settings achieve 51 FPS average, which is just below the 60 FPS threshold but playable with adaptive sync. Medium settings produce 34 FPS average, with a minimum of 29 and maximum of 39 FPS, showing a tight but low range. High settings deliver 29 FPS average, and Ultra falls to 22 FPS average. The 1440p data suggests that Low settings are the only viable option for a consistent experience, and even then, the FPS is not high.

At 3840x2160, the combo is not playable. Low settings yield 30 FPS average, which is borderline but likely to feel stuttery in Rust's demanding environments. Medium settings produce 20 FPS average, with a minimum of 17 and maximum of 23 FPS. High settings deliver 17 FPS average, and Ultra drops to 13 FPS average. The 4K data is uniformly poor, with no settings preset reaching 60 FPS or even 30 FPS reliably; only Low settings touches the 30 FPS mark.

The min and max FPS data for Medium settings across resolutions shows consistent behavior: at 1080p, the range is 42-57 FPS (a 15 FPS spread), at 1440p the range is 29-39 FPS (a 10 FPS spread), and at 4K the range is 17-23 FPS (a 6 FPS spread). This narrowing range at higher resolutions further indicates GPU saturation, where the card is consistently pegged at its maximum load.

CPU Role

The AMD Ryzen 5 7400F is a 6-core, 12-thread processor based on Zen 4 architecture, built on TSMC's 5 nm process. It has a base clock of 3.70 GHz and a boost clock of 4.70 GHz, with 32 MB of shared L3 cache. In synthetic benchmarks, it scores 21765 in Cinebench R23 multi-core and 3072 in single-core, placing it in the 83rd percentile of all CPUs. These scores indicate strong single-threaded performance, which is crucial for Rust's engine that relies heavily on a few main threads.

Despite the CPU's capability, the measured FPS data shows it is not the limiting factor. At 1080p Low, the 74 FPS average is likely near the CPU's maximum frame rate for Rust given the GPU's rendering speed. The CPU's Passmark single-thread score of 3689 and multithread score of 25645 are both robust, suggesting it could feed a more powerful GPU. The Cinebench R20 single-core score of 1290 confirms that the processor's per-core performance is high enough to avoid bottlenecking in most scenarios.

The CPU's 6 cores and 12 threads are sufficient for Rust's background simulation and entity processing. Rust is known to be CPU-intensive in multiplayer servers with many players and structures, but the benchmark data shows that at these GPU-limited frame rates, the CPU has ample headroom. The Ryzen 5 7400F's memory bandwidth of 83.2 GB/s (DDR5 dual-channel) also helps with data-heavy tasks, though the GPU's 256.0 GB/s bandwidth is the more critical figure for frame rendering.

The data suggests that pairing this CPU with a much stronger GPU would yield significantly higher FPS in Rust. The CPU's average benchmark score of 32750 is nearly identical to its nearest rivals, with deltas of just 0.1-0.3%, indicating it is well-positioned in the mid-range CPU market. However, in this combo, the CPU's potential is unrealized due to the RX 580's limitations.

Settings Recommendations

Based on the measured FPS data, the optimal settings preset depends on the user's resolution and performance targets. At 1920x1080, the Low preset is the only option that consistently exceeds 60 FPS, with an average of 74 FPS. This provides the smoothest experience for fast-paced combat and building. The Medium preset at 49 FPS average is a reasonable compromise if visual quality is prioritized, but the 25 FPS penalty compared to Low may be noticeable. High at 42 FPS and Ultra at 32 FPS are not recommended for 1080p, as they fall below the 60 FPS threshold and may cause input lag in a game where survival depends on quick reactions.

At 2560x1440, Low settings are the only viable choice, delivering 51 FPS average. Medium at 34 FPS is playable but will feel sluggish in intense moments. High and Ultra at 29 FPS and 22 FPS respectively should be avoided. For 1440p users, the recommendation is to stay on Low settings and consider lowering the resolution to 1080p if a more stable frame rate is desired.

At 3840x2160, no settings preset is recommended for serious play. Low settings at 30 FPS average is the best achievable, but Rust's large open world and frequent asset loading will likely cause noticeable stuttering. Medium at 20 FPS and below is unplayable. Users with 4K monitors should either reduce the resolution to 1440p or accept the Low settings experience.

The best overall experience is 1080p with Low settings, achieving 74 FPS average. This provides a smooth, responsive experience that leverages the CPU's strong single-threaded performance while minimizing the GPU's workload. For players who value visual fidelity over frame rate, 1080p Medium at 49 FPS is the highest setting that maintains a playable frame rate, with the minimum of 42 FPS still above 30 FPS. The data shows that this combo cannot handle Ultra settings at any resolution without dropping below 32 FPS average, making that preset effectively unusable for this hardware pairing.
